Active Network announced this morning that its top two executives had resigned immediately. A spokesperson told Runner's World Newswire the resignations are unrelated to recent high-profile registration problems at the Chicago and Marine Corps marathons, which used Active as their registration provider for this year's races.

Matthew Landa and David Alberga resigned as CEO and chairman of the board, respectively, effective immediately, the company announced in a press release today.

"Running is part of our business, but it's not the whole of our business," Carroll said.

The Chicago Marathon opened registration for its 2013 running on February 19. Registration, which was through Active, was suspended three hours later because of technical issues. The marathon wound up going to a lottery system two weeks later to fill the 15,000 spots that remained after registration was suspended.

Registration for the Marine Corps Marathon opened on March 27 via Active. The race filled its field that day, but would-be registrants reported repeated technical problems. The marathon later apologized for the registration process.

Chicago and Marine Corps have said they're considering other registration processes for their 2014 editions. When asked whether Active would be handling registration for the marathons in 2014, Carroll said, "I can't comment on future contracts."
